Cabin was spacious enough for 2 people. Bed and pillow were amazingly comfortable. Furniture was slightly dated as was the shower area. Loved to turn the air to a higher temperature and sleep with the balcony door open.
Deck 7 · Port · ForwardNice cabin and a great location. Easy access to the Promenade and the theater. The balcony was small. There was room for two chairs and a table. The sliding glass door was hard to open and close. Limited outlets. Very dark in the room. I would suggest a night light.
